摘要 :
A driver circuit receiving wireless communication over a wireless network is disclosed. The driver circuit includes a lighting load, a main driver, and an auxiliary driver. The lighting load is selectively illuminated based on an output voltage being provided to the lighting load that is at least a forward voltage of the lighting load. The wireless communication is indicative of whether the lighting load is to be illuminated. The main driver is for controlling current and voltage within the driver circuit such that if the wireless communication indicates the lighting load is to be illuminated, then the current delivered to the lighting load is regulated by the main driver, and if the wireless communication indicates the lighting load is not to be illuminated, then the output voltage delivered to the lighting load is controlled by the main driver is below the forward voltage.
